The first alpha release of the GTK+ based version of CASMSIM is now available. For now it only simulates the HP-45, but the HP-35 and HP-55 will be added back in soon.

Added a menubar, although most of the menu commands aren’t implemented yet. File/Quit and Help/About are the only ones that work at the moment.

Gotta figure out why the undocumented HP-45 stopwatch mode doesn’t work right. It worked on the xlib version. I had a theory that it was aliasing of the simulation timing with the display update timing, but changing the display update rate doesn’t fix it.

I’ve started adding a debugger.
